Answered: I need to use two APIs to get one result. How?

I need to send my lat/long coordinates to one API and get the results in JSON. The results contain the converted ArcGIS X/Y points from my lat/long. I then need to send those X/Y points to a 2nd API and show those results (coming to me in JSON) on my View.

What is the best way to do this? The only thing that comes to mind is two different Stores and Proxies and playing ping pong until I have the finished product. I'm sure there is a much cleaner solution. Suggestions?
